Hello everyone, i've been searching all over the internet since 1 week and i didn't find what i was looking for. As mentionned, i am trying to open very large products in catia (up to 150Mb) and it's taking like 10 minutes to load. I'm on Win7 16Go Ram. I already tried all technics in catia (cach on...) but that doesn't seem to improve anything. I was just wondering if 3D XML files are possibly the solution for my problem? Are they lighter? Is displaying 3D XML files in 3D XML Player smoother than opening equivalent CATProducts in Catia?
